Abstract
The utility model discloses a self-closed monofilm air diffuser which comprises a monofilm rubber diaphragm and a cylindrical air out device. The self-closed monofilm air diffuser is provided with a monofilm rubber diaphragm positioning pipe which is used for positioning and connecting an air supply duct. The center position of the cambered bottom of the monofilm rubber diaphragm positioning pipe is provided with a section of air inlet pipe which extends into the air supply duct. The upper end of the air inlet pipe is communicated with two air out ducts which are oppositely arranged and are inclined and upward. The monofilm rubber diaphragm is arranged at the upper port position positioned on the air out duct of the air inlet pipe in the monofilm rubber diaphragm positioning pipe, and the upper surface of the monofilm rubber diaphragm is provided with the cylindrical air out device. The utility model has the advantages of reasonable design, convenient installation, small output bubble diameter and large bubble distribution range. The utility model can resist stacking and pressing of filtering material and isn't easily blocked by foreign matters.
Description
Technical field
The utility model relates to a kind of air diffuser of oxygen supply in the filter material layer of BAF, particularly a kind of self-closing's single hole film air diffuser.
Background technology
At present, in ordinary biofilter,, normally ventilation hole is set, relies on the natural ventilation oxygen supply in the bottom, filter tank for the microorganism needed oxygen of surviving is provided.Be in operation and cause air feed barometric distribution inequality on the height of whole filter tank easily, form channel and short stream, also easily form bubble simultaneously, the stifled phenomenon of local gas takes place, and the quality of natural ventilation oxygen supply also is limited by poor, filter tank height, filtrate voidage and the wind-force of temperature and temperature in the pond, can not provide than the stabilized uniform ventilation to the filter tank.The BAF technology has solved the deficiency of above-mentioned technology preferably.
The utility model content
The purpose of this utility model is on the basis of BAF technology, provide a kind of easy for installation, confess that bubble diameter is little, the bubble distribution range is big, be difficult for being stopped up, be not afraid of self-closing's single hole film air diffuser that the filtrate heap is pressed by foreign material.
For achieving the above object, the technical scheme that the utility model adopted is: a kind of self-closing's single hole film air diffuser, comprise single hole rubber diaphragm 2, tubular air-out apparatus 3, it is characterized in that: self-closing's single hole film air diffuser is provided with and is used for the single hole rubber diaphragm positioning pipe 1 that is located by connecting with steam line 6, be provided with one section inlet pipe 5 that stretches in the steam line 6 in the mid-way of single hole rubber diaphragm positioning pipe 1 curved bottom, the upper end of inlet pipe 5 is communicated with two and is oppositely arranged, the outlet pipe 4 of oblique top, single hole rubber diaphragm 2 places the outlet pipe 4 upper port positions that are positioned at inlet pipe 5 in the single hole rubber diaphragm positioning pipe 1, is provided with tubular air-out apparatus 3 above the single hole rubber diaphragm 2.
The utility model compared with prior art has the following advantages:
1, reasonable in design, easy for installation.
2, the output bubble diameter is little, the bubble distribution range is big.
3, be not afraid of the filtrate heap and press, be difficult for being stopped up by foreign material.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model comprises single hole rubber diaphragm 2, tubular air-out apparatus 3, it is characterized in that: self-closing's single hole film air diffuser is provided with and is used for the single hole rubber diaphragm positioning pipe 1 that is located by connecting with steam line 6, be provided with one section inlet pipe 5 that stretches in the steam line 6 in the mid-way of single hole rubber diaphragm positioning pipe 1 curved bottom, the upper end of inlet pipe 5 is communicated with two and is oppositely arranged, the outlet pipe 4 of oblique top, single hole rubber diaphragm 2 places the outlet pipe 4 upper port positions that are positioned at inlet pipe 5 in the single hole rubber diaphragm positioning pipe 1, be provided with its top above the single hole rubber diaphragm 2 the tubular air-out apparatus 3 of shutter 8 is housed, shutter 8 is provided with production well 7, air-out apparatus 3 has prevented that effectively filtrate heap from pressing and the foreign material obstruction, and what guaranteed to give vent to anger is unimpeded.
During the utility model work, air in the steam line 6 is through inlet pipe 5 and outlet pipe 4 bottom to single hole rubber diaphragm 2, and with single hole rubber diaphragm 2 jack-up upwards, fenestra 9 is opened, air is overflowed by fenestra 9, and is air bubble-shaped and enters the filter tank through tubular air-out apparatus 3.During air feed, the fenestra 9 of single hole rubber diaphragm 2 is not closed automatically, prevents that the sewage in the filter tank from flowing to steam line 6.
Claims (2)
